Abstract

1337449 Vinylidene fluoride copolymers E I DU PONT DE NEMOURS & CO 19 April 1971 [2 April 1970] 26047/71 Heading C3P Vinylidene fluoride copolymers are obtained in an aqueous medium containing a watersoluble free radical initiator and a water-soluble hypophosphite. Examples relate to the continuous emulsion polymerization of vinylidene fluoride and hexafluoropropylene using sodium persulphate and sodium hypophosphite. The vulcanized products have improved heat ageing properties.
